title: 3-[(E)-(Benzyl-iminiumyl)meth-yl]-6,8-di-chloro-2H-chromen-4-olate.
abstract: In the title compound, C17H13Cl2NO2, the H atom of the -OH group is transferred to the N atom of the imine, forming a zwitterion. Thus, there is a intra-molecular O⋯H-N, rather than O-H⋯N, hydrogen bond, which forms a six-membered ring.
